The vocalist and the song sounds like Passion Pitt. To make it more complicated, subtract Passion Pitt’s electro-spastic sound, add some good ol’ guitars, and top it off with “oooooohs” straight of out a Kings of Leon song and you’ve got this.
My sister told me about this earlier this summer. Apparently the guy holding the quaffle worked with her in a bio lab back home. I died when she said “The snitch on this guy’s team is the fastest guy on the cross country team dressed in yellow.”
